Examples
The following example demonstrates how to use the CurrentItem property to make changes when an item is selected. It assumes that you have a form that contains a bound DataRepeater named DataRepeater1, a bound TextBox named UnitsInStockTextBox, and a Label named LowStockWarningLabel.
Private Sub DataRepeater1_CurrentItemIndexChanged(
) Handles DataRepeater1.CurrentItemIndexChanged
' Exit if the control is first loading.
If DataRepeater1.CurrentItem Is Nothing Then Exit Sub
' Check for zero or negative quantity.
If CDbl(
DataRepeater1.CurrentItem.Controls("UnitsInStockTextBox").Text
) < 1 Then
' Display a the warning label on the form.
Me.LowStockWarningLabel.Visible = True
Else
Me.LowStockWarningLabel.Visible = False
End If
End Sub
private void dataRepeater1_CurrentItemIndexChanged(object sender, System.EventArgs e)
{
// Exit if the control is first loading.
if (dataRepeater1.CurrentItem == null) { return; }
// Check for zero quantity.
if (dataRepeater1.CurrentItem.Controls["unitsInStockTextBox"].Text == "0")
// Display a the warning label on the form.
{
this.lowStockWarningLabel.Visible = true;
}
else
{
this.lowStockWarningLabel.Visible = false;
}
}
